Utilities for Chakobsa scripts. Implements {{chak-from-root}}
.
Exposed functions
l(term, face, alt)
- Creates a link to a Chakobsa lexeme - similar to
{{l|chak|term}}
is_geminate(char)
- returns true if the supplied 'character' is geminate
compress_consonants(str)
- Returns a 'compressed' version of the string where consonant digraphs are reduced to a single character and trigraph geminates are reduced to a geminate of a single character. Mostly for use with other functions for parsing.
expand_consonants(str)
- Returns an 'expanded' version of the string where reductions from
compress_consonants
are replaced with the original romanizations.
parse_consonants(str)
- Returns a string where the consonants have been split out, delimited by hyphens. Understands geminate consonants and considers them a 'single' consonant.
parse_root(root_str,expandFinal)
- Returns a table of parts of the root string is grouped by consonant and vowels. Example: "kkaalatg" > "kk","aa","l","a","tg". If expandFinal is true, returns the final part parsed out through
parse_consonants
The above example would be "kkaalatg" > "kk","aa","l","a","t-g". Used for inflection functions.
